This is less than awesome:
$ ./perl6 -e 'my $a = Numeric.new; say $a + 0'
[hangs]
^C
With the Numeric class being as abstract as it is, it doesn't make a whole
lot of sense to be able to instantiate it directly. But the language
seems to like making everything being instantiable. Given that it is
instantiable, having a Numeric object that hangs on addition is less
than awesome. I guess there's some method delegation going on that
loops back to itself, because nothing has said concretely how to add a
Numeric to an Int. It would be better for the lack of specific method
to be detected and signal an error.
